Health Risk Assessment of Waste Incineration at Rizgary Teaching Hospital, Iraq: A Study of Pollutant Emissions and Exposure
The incineration of waste is a common practice in many hospitals around the world, including Rizgary Teaching Hospital in Iraq. However, this practice has raised concerns about the potential health risks associated with the emission of pollutants into the environment. The objective of this study is to assess the health risks associated with waste incineration at Rizgary Teaching Hospital, with a focus on pollutant emissions and exposure.
Introduction
Waste incineration is a process that involves the burning of waste materials, such as medical waste, at high temperatures. This process is often used in hospitals as a means of disposing of infectious and hazardous waste. However, the incineration of waste can result in the emission of pollutants, such as particulate matter, carbon monoxide, and volatile organic compounds, into the environment. These pollutants can have adverse effects on human health, particularly for people living in close proximity to the incineration facility.
Background
Rizgary Teaching Hospital is a major healthcare facility located in Erbil, Iraq. The hospital generates a significant amount of waste, including medical waste, which is incinerated on site. The incineration facility at the hospital is a simple, non-combustion type incinerator that burns waste at temperatures between 800-1000°C. However, the facility lacks proper emission control systems, which can lead to the release of pollutants into the environment.
Methodology
This study was conducted over a period of six months, during which time air samples were collected from the surrounding area of the hospital. The samples were analyzed for particulate matter (PM), carbon monoxide (CO), and volatile organic compounds (VOCs). Additionally, a questionnaire survey was conducted among hospital staff and nearby residents to assess their exposure to pollutants and any resulting health effects.
Results
The results of the study showed that the incineration of waste at Rizgary Teaching Hospital resulted in the emission of significant amounts of pollutants into the environment. The levels of PM, CO, and VOCs in the air samples collected from the surrounding area were found to be higher than the recommended limits set by the World Health Organization (WHO). The questionnaire survey revealed that hospital staff and nearby residents were exposed to these pollutants, and reported a range of health effects, including respiratory problems, headaches, and eye irritation.
Discussion
The results of this study highlight the potential health risks associated with waste incineration at Rizgary Teaching Hospital. The emission of pollutants, such as PM, CO, and VOCs, can have adverse effects on human health, particularly for people living in close proximity to the incineration facility. The lack of proper emission control systems at the hospital’s incineration facility is a major concern, as it allows pollutants to be released into the environment. Additionally, the findings of this study suggest that hospital staff and nearby residents are at risk of exposure to these pollutants, which can result in a range of health effects.
Health Risks
The health risks associated with waste incineration at Rizgary Teaching Hospital are significant. Exposure to PM, CO, and VOCs can cause a range of health effects, including:
- Respiratory problems: PM can cause irritation to the eyes, nose, and throat, and can exacerbate conditions such as asthma and chronic obstructive pulmonary disease (COPD).
- Cardiovascular disease: Exposure to PM and CO can increase the risk of cardiovascular disease, including heart attacks and strokes.
- Cancer: Some VOCs are known to be carcinogenic, and exposure to these compounds can increase the risk of cancer.
- Neurological problems: Exposure to VOCs can cause neurological problems, including headaches, dizziness, and nausea.

The incineration of waste at Rizgary Teaching Hospital poses significant health risks to hospital staff, nearby residents, and the environment. The lack of proper emission control systems at the hospital’s incineration facility allows pollutants to be released into the environment, which can have adverse effects on human health. It is recommended that the hospital takes immediate action to upgrade its incineration facility and implement proper emission control systems. Additionally, hospital staff and nearby residents should be educated on the potential health risks associated with waste incineration and take steps to minimize their exposure to pollutants.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Upgrade the incineration facility at Rizgary Teaching Hospital to include proper emission control systems, such as scrubbers and filters.
- Implement a regular maintenance program for the incineration facility to ensure that it is operating efficiently and effectively.
- Educate hospital staff and nearby residents on the potential health risks associated with waste incineration and provide them with information on how to minimize their exposure to pollutants.
- Conduct regular air quality monitoring to ensure that the levels of pollutants in the surrounding area are within recommended limits.
